我遇到了listview与内部片段一起使用的问题，这些内部片段位于This git hub example中给出的导航抽屉页面滑动标签条视图标签中。
我正在使用相同的示例，并且所有4个选项卡都有一个列表视图，其中不同的arraylist设置为适配器。
我只使用一个片段和标签位置的基础我正在将不同的列表数据加载到内部片段arrayAdapter。我还有两个按钮，一个是删除，另一个是添加。
我想要什么：如果我按下添加按钮，那么它应该将新数据添加到数组列表中（基于选项卡位置将新添加添加到相应的arrayList）并刷新listview数据。
在我的代码中刷新当前查看选项卡，但在下一个选项卡列表视图中还刷新并获取上一个选项卡的数据。请帮助我，任何帮助将不胜感激。
我有单一类文件。如果我的方法有误，请告诉我正确的方法。
